Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.

The Museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Other artifacts range from personal computers to ENIAC, the Altair, and the Osborne 1. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

Jack Kilby’s demonstration of the first working integrated circuit (IC) in 1958 revolutionized the field of microelectronics. Instead of using discrete transistors, resistors, and capacitors to form a circuit, Kilby’s IC design integrated a transistor, a capacitor, and the equivalent of three resistors all on the same chip. Kilby fabricated three types of circuits to test his idea: a flip flop, a multi vibrator and a phase shift oscillator. This chip is the phase-shift oscillator.

The first IC was made out of a thin slice of germanium (the light blue rectangle) as a bulk resistor and contained a single bipolar transistor (under the large aluminum bar in the center). It had four input/output terminals (the small vertical aluminum bars), a ground (the large bar on the far right), and wires of gold. The microchips of today have been improved by hundreds of innovations, but Kilby’s prototype was an important early step.

This Sholes, Glidden, & Soule typewriter patent model was awarded patent number 79,265 on June 23rd, 1868. C. Latham Sholes, Carlos Glidden, and Samuel Soule were living in Milwaukee, Wisconsin when they began to make progress towards a commercially viable type-writing machine after several aborted attempts. The improvements named in this patent include a “better way of working type bars, of holding the paper on the carriage, of moving and regulating the movement of the carriage, of holding and applying the inking ribbon, a self adjusting platen, and a rest or cushion for the type-bars.” Many early typewriters used piano keys in their designs, including this model with only six keys.

The Royal Typewriter Company manufactured this Royal Magic Margin typewriter around 1940. The typewriter’s patented Magic Margin design allowed the typist to set both the left and right hand margins with a simple push of a lever. With easy margin-switching, the Royal KMM could easily address envelopes, tabulate figures, and create tables.

The Royal Typewriter Company was founded in 1906 by Thomas Fortunes Ryan and Edward B. Hess, with Ryan providing the capital and Hess providing the inventiveness. Hess owned over 150 patents, many of which were assigned to the Royal Typewriter Company. Hess’s most noteworthy patents related to increasing the ease of typing, including an accelerating typebar, anti friction roller escapement, Magic Margins, and selective touch control.

In the early 1970s, most personal computers came as hobbyist kits requiring a high level of technical expertise to assemble. Don French, a buyer for the consumer electronics chain Tandy Radio Shack (TRS), believed that Radio Shack should offer an assembled personal computer and hired engineer Steve Leininger to design it. In the summer of 1977, Radio Shack introduced the TRS-80 for $599. This offering included a BASIC language interpreter, four kilobytes of RAM, a Zilog Z80 processor at 1.77 megahertz, a twelve-inch video monitor, a cassette recorder, a power supply, and a cassette tape containing the games Blackjack and Backgammon. While some Tandy executives were skeptical about the success of the PC market, the availability of the TRS-80 on five thousand Radio Shack store shelves helped the Model 1 sell over one hundred thousand units during its first year, which was 50 percent of the total PCs sold in 1978.

The TRS-80 had its microprocessor inside its keyboard. While you could purchase just the TRS-80 for $400, most opted for the package that included the twelve-inch monitor and cassette recorder for $600. This object includes the TRS-80 Expansion Interface for $299 (below monitor) that gave the machine an extra thirty-two kilobytes of memory; the TRS-80 Telephone Interface II for $199 (far left) that allowed for network communication; two Mini-Disk drives for $499 (right of monitor); and printer for $399 (far right).

In the summer of 1977, Radio Shack introduced the TRS-80 for $599. You could purchase the computer without a display for $399.95, but the most common configuration was buying the computer, monitor, and datacassette recorder for $599.

This is a Federal Express SuperTracker handheld barcode scanner, first introduced in 1986. The SuperTracker is a critical part of FedEx’s Customers, Operations, and Services Master On-line System (COSMOS) used to track packages and confirm deliveries. Customer agents, couriers, and sorting personnel use the SuperTracker to scan barcodes on packages as they move through the Federal Express system. Providing information about a package’s location, status, and movement became an integral part of delivery companies, with every major carrier implementing a package tracking system.

This rectangular orange plastic desk sign reads "THINK" in black lettering. “THINK” was the slogan developed by Thomas Watson Sr. when he was a sales manager for the National Cash Register Company, exhorting his salesmen to use their heads, not their feet—their job was to think. As IBM CEO during the 1920s, Watson continued to encourage innovation and “THINK” became a ubiquitous slogan in IBM paraphernalia including notepads, advertising, products—even the title of the company magazine. By the 1950s, IBM sales staffs distributed “THINK" signs like this one to their customers. An IBM customer representative gave the donor this sign.

This packet of materials was provided to the donor when he took a course on the use of tabulating equipment at IBM in Endicott, New York, in the 1950s. Included are a name tag, a punch card, three postcards, two leaflets, and an envelope.

Apple released the Newton MessagePad Model H1000 in 1993 as one of the first personal digital assistant (PDA) devices. The device sported a 20 megahertz ARM 610 processor with 630 kilobytes of RAM and was powered by four AAA batteries. The MessagePad was designed to store contacts, notes, and calendars, and to provide word processing and rudimentary Internet browsing. The MessagePad’s most revolutionary feature was that it accepted handwriting input via a pen stylus. The novelty of handwriting recognition soon became notorious due its buggy translations, lampooned in popular culture, most notably in a week of Doonesbury comic strips.

Not long after Intel introduced its 8080 microprocessor, a small firm in Albuquerque, New Mexico, named MITS (Micro Instrumentation and Telemetry Systems) announced a computer kit called the Altair, which met the social as well as technical requirements for a small personal computer. MITS succeeded where other, more established firms had failed, and it was their machine that inaugurated the personal computer age. MITS got its start in computing in 1971, when it introduced an electronic calculator kit. Several thousand sold before 1974, when the sharp reduction in calculator prices drove the company out of that market.

H. Edward Roberts, the Florida-born former U.S. Air Force officer who headed MITS, decided to design a small, affordable computer around the Intel 8080. His daughter named the new machine after the star Altair. It was the first microcomputer to sell in large numbers. In January 1975, a photograph of the Altair appeared on the cover of the magazine Popular Electronics. The caption read “World's First Minicomputer Kit to Rival Commercial Models.” According to the magazine, the machine sold as a kit for $395, and assembled for $498. Roberts had hoped to break even by selling 200 Altairs. Within three months he had a backlog of 4,000 orders.

Enthusiasm for the Altair and other personal computers spawned computer hobbyist clubs, computer stores, newsletters, magazines, and conventions. By 1977, a host of companies, large and small, were producing microcomputers for a mass market. This phenomenon was abetted by a design decision to make the Altair an "open" machine. In other words, it passed data along a channel called a bus, whose specifications were not kept a secret. That way both MITS and other companies could add memory cards, cards to control a printer or other devices as long as they adhered to the published standards.

This particular Altair was collected by the Smithsonian because it documents how hobbyists would outfit the machine with additional parts and components. The user added his own keyboard, monitor, disk drive, and 17 plug-in boards to expand the computer’s capability. Unfortunately, the original owner of the kit is unknown. The computer was donated to the Smithsonian by a second owner, Mark Sienkiewicz, who purchased it as a collectable item and never used it.
